지역기반 원격근무를 통한 출근 통행거리 저감이 CO<sub>2</sub> 배출에 미치는 영향: 수도권 지역을 대상으로
강지한,오규식,Kang, Jihan,Oh, Kyushik 한국공간정보학회 2014 한국공간정보학회지 Vol.22 No.4
우리나라에서 지역기반 원격근무센터의 설치와 운영은 시범적 초기단계로서, 재택근무에 대한 연구가 다소 이루어진 바 있지만, 지역기반에서 원격근무센터가 본격적으로 확대 보급되었을 때의 효과를 분석한 연구는 미비하다. 이에 본 연구에서 수도권 지역을 대상으로 원격근무센터의 설치를 통해 얻을 수 있는 출근 통행거리의 저감 효과를 네트워크를 기반으로 분석하고, 이를 통해 지역기반 원격근무센터의 $CO_2$ 저감효과를 정량적으로 산출하였다. 분석결과, 지역기반 원격근무센터로 인한 총 $CO_2$ 저감량은 1일 기준 911 톤(Ton)으로 나타났다. 이같은 분석 결과에 1년 근로일수(통계청)인 258일을 적용하면 연간 235,056톤(Ton)의 $CO_2$가 원격근무센터 설치에 의해 저감될 수 있다. 본 연구는 원격 근무센터 설치를 통해 얻을 수 있는 환경적 효용을 정량적으로 산출함으로써 향후 원격근무센터의 효과적 입지를 위한 가이드라인으로 활용이 가능하며, 행정구역별 비교를 통해 원격근무센터 확대 실시에 있어 우선순위 결정에 도움을 줄 수 있을 것이다. The establishment and operation of Region-based Teleworking Centers(RTC) in Korea is in the initial stage at the moment. Although some studies have been conducted on telecommuting at home, few studies have been performed on the effects of all-out expansion and diffusion of region-based Teleworking Centers. Therefore, this study analyzed the reduction effect of commuting distance which is possible to obtain from the establishment of Teleworking Centers, based on the network in the Seoul Metropolitan Area, Subsequently, quantitative reduction of the effects of $CO_2$ were calculated from region-based Teleworking Centers. The results of the analysis indicated that region-based Teleworking Centers could reduce a total of 911 tons of $CO_2$ per day. When applying these results to 258 working days per year (according to Statistics Korea), 235,056 tons of $CO_2$ can be reduced annually by the establishment of Teleworking Centers. With quantity on environmental utility to be obtained from the establishment of Teleworking Centers, this study can be utilized as a guideline for selecting effective locations of Teleworking Centers in the future. It can also be helpful in decisions to determine the priority of extending operations of Teleworking Centers through comparisons among administrative districts.

아파트 리모델링 수직증축 허용에 대응한 서울시 정책방향
권영덕(YoungDuk Kwon),고준호(JunHo Ko),강지한(JiHan Kang) 서울연구원 2014 서울연구원 정책과제연구보고서 Vol.- No.-
The purpose of the study is to identify the major impacts on housing supply and transportation according to the alleviation of floor limitation in apartment remodeling and to present improvement of current policies. Apartment remodeling policy allowing to the alleviating height control(vertical extension) is to allow constructing two to three floors higher than the existing building, increase in the 15 percent of households, and selling out the increasing parts of the apartments. The method is to review impacts on possible infringement of the right of daylight sunshine amount and problems of FAR management according to floor number increase. And, it is to identify parking difficulties and transportation impacts according to the increase in the number of households and cars. It is, then, to identify securing feasibility according to parcel out of the extra apartments. Finally, it is to identify possible number of housing supply reviewing the physical condition of the apartment sites. Its impacts are identified on the first building with 90 percent and more, second and third buildings with 50 percent and more in terms of the infringement of day light amount from remodeling. Thus, it is difficult of the apartments with 3 buildings or less to do vertical extension remodeling. In order to do vertical extension remodeling for the apartments in a district plan with height control, there should be a rest of 15 percent more below legal FAR in the existing sites. Buildings needed structure reinforcement are apartment sites with earthquake-proof design standard, 16 percent and apartment sites falling short of current earthquake-proof design standard, 71 percent respectively. The possible numbers of housing supply, satisfying physical condition and project possibilities are currently 40,964 units and 55,625 units for the future in year 2024 standards. As a result of the transportation environment effect in Seoul due to the increase in the number of vehicles on the roads, it is shown that gross trip distance increases between 0.14 and 2.16% currently and gross trip time, 0.25~3-83% respectively while gross trip distance increases 0.17~3.83% and gross trip time, 0.30~6.31% in 2024. It becomes different in terms of transport effects on road by the increase in household sizes and choice of transport modes. However, the increase in the use of public transit can solve this kind of transport problems. Policy directions are focused on securing citizen safety, solution to the inconvenience of the life, sustainable development, and lengthening the longevity of housing. And policies are improved so as to shift from profitability, to manage considering a life cycle of apartments, to differentiate public supports about vertical extension and repair-type remodeling, and to maintain institutional amendments. Improvements related to the right of daylight sunshine amount are needed to readjust rationally the control of the right and to minimize unqualified buildings due to the applying of the new standard. Parking space is sufficiently secured toward increase in the number of the households, however problems related to the traffic volume in the sites can be solved by inducing public transit usage. Besides, these are recommended to pursue demonstration projects by the public in order for low-cost type remodeling to settle down, to encourage cost savings applying various public supports, to reinforce administrative organization.
